1 Claim. 1

This invention relates to improvements in the construction of tanks,silos and like vessels.

The present invention relates to construction of vessels of concrete andparticularly to one wherein a plurality of staves are provided and aresecured together by several hoops which encircle the assembled,positioned staves. It is, of course, well known to manufacture vesselsof this character from Wood staves, each of which is cut in such amanner that the butting edges coincide with the radii of the finalvessel. In ac cordance with this invention, the staves are fashioned ofconcrete and are held together by several encircling hoops. To ensurethat the concrete staves can be formed without use of a complicated moldand to obviate any final finishing operation, I provide, between eachadjacent pair of concrete staves, an abutment member or spline whichprovides the contact between the staves, joining the staves in a sealingengagement. Utilization of this construction enables me to case thestaves using simple forms so that the final tank construction is quiteinexpensive and is competitive with wood tanks.

It is the generally broad object of the present invention to provide animproved, concrete stave construction which can be utilized in providingtanks, silos and like vessels.

The invention includes other objects and features of advantage, some ofwhich, together with the foregoing will appear hereinafter wherein thepresent preferred construction of this invention is illustrated.

Referring to the drawing accompanying and forming a part hereof, Figure1 is a section taken transversely through the wall of a tank constructedin accordance with the present invention.

Figure 2 is a side elevation with two different portions of the tankbroken away to illustrate the side wall construction and the detail ofconstruction utilized to provide the juncture between adjacent concretestaves.

Referring to the drawing, 1 provide a plurality of staves indicatedgenerally at 6 and of a height corresponding to that desired for thevessel. Each stave is case of concrete, includes an arcuate inner face 1and an arcuate outer face 8, the latter being additionally relieved asat 9 to provide a recess in which battens iii are mounted when thestaves are assembled. The side edges H and [2 of each stave fall alongthe radii of the final vessel, each stave representing an arcuatesegment taken between two circles, the distance between the two circlescorresponding to the depth of the stave, and the arcuate length of thesegment corresponding to the angular width of the particular are appliedto the circles. Each stave can include steel reenforcement which I havenot shown in the drawing.

In accordance with this invention, sides I l and E2 of each stave arerecessed as at I4 about midway along each edge. Preferably, each recessis V-shaped in outline. Between adjacent staves and in the cooperativelypositioned recesses 14 is mounted a wood spacer or spline [6 of aconfiguration adapted to fit in and seal the space between the adjacentstaves. In the drawings I have shown spacer 16 as square in crosssection and fitting into the two adjacent V-shaped recesses M. Thisconstruction has proven quite useful. Spline l6 can also be madecircular in section, recesses M then being fashioned so as to fit aspacer of this section.

The staves are assembled in much the same manner as is usual forassembly of a vessel fashioned of such elements. Thus, assuming that asuitable bottom or base has been provided, it is only necessary to mountthe staves in an upright position on this, splines 46 being positionedbetween recesses M on the adjacent staves. At the same time, theencircling hoops I l are applied over battens It, the hoops beingfinally drawn up tight in the usual manner to ensure that the vessel isfluid tight.

Provision of the splines between the staves permits the latter to bemade with a generally rectangular cross-section for the splines spacethe staves apart and sides I! and I2 need not fall along the radii ofthe tank. The splines can also be made of wood with a cross-sectioncorrespond ing to an equilateral triangle, the base of which is engagedwith the adjacent staves.

I claim:

A vessel of the character described consisting essentially of aplurality of substantially vertical precast concrete staves arranged ina side by side relationship and extending from the bottom to the top ofthe vessel, each stave being substantially rectangular in horizontalsection and having an inner and an outer vertical face and verticalsides arranged at a radial angle to one another, each side having alongitudinal V-shaped recess along each vertical face thereof andintermediate the inner and outer faces of the stave, a rectangular woodspacer positioned between each adjacent stave pair in engagement withthe vertical V-shaped recesses therein, and maintaining adjacent stavesin a spaced relationship, the outer vertical face of each stave beingrecessed 3 adjacent each side thereof to provide a recess in REFERENCESCITED the front face of the stave for a batten, a vertical batten fittedinto the vertical recesses in each adgg 3 g i f i are of lecord m thejacent stave pair and covering the space between the adjacent stave pairand extending out beyond UNITED A S PA ENTS tilif stave pair, and hoopspositioned over said Number Name Date b ttens for retaining said stavesin sealing en- 353,696 Hubbard May 14, 1907 gagement with said spacersand for retaining 1,109,566 Brookshire Sept' 1 1914 said battens inposition on said stave pairs. 1,383,166 Steinkraus June 28: 19212,074,592 Rowell Mar. 23, 1937 MARK LINTZ.
